'wEEn-nEs'rao me MACHINE.

Application filed'Jan'uary 20, 1920. Serial no. 352,722.

To all to hem it may concern Be it known that LEDWARD LAMBERT, a citizenof the United States, residing at Convent, in the parish of'St' James,State of Louisiana, have invented a new and'useful VVeed-DestroyingMachine; and Ido hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention relates to weed destroying machines and particularly tomachines adapted for burningand destroying weeds in ditches or the like.a r a A further object is to provide a machine of this charactercomprising a fuel tank mounted on a wheeled body, said wheeled bodybeing adapted to straddle a ditch and to provide a horizontally disposedburner having a centrally disposed downwardly extending segmentallyshaped portion adapted to register with a ditch andbe disposed thereinso that as the vehicle advances, said burner to which fuel oil isconducted by means of piping will burn the trash and weeds within theditch, and means for raising the burner out of the ditch when desired.It is also the object of the invention to provide flame shields on eachside of the burner whereby the flames will be prevented from damagingplants growing on either side of the ditch.

With the above and otherobjects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the machine SllOWlIlgthe burner disposed in a ditch.

Figure 2 is a plan view of the machine.

Figure 3 is a perspective view of the burner, and the pipes leadingthereto.

Referring to the drawings, the numeral 1 designates a frame, said framebeing provided with a transversely disposed axle 2, 0n the ends of whichwheels 3 are rotatably mounted. The forward end of the frame is providedwith single trees 4, to which draft animals may be attached for movingthe vehicle as a whole forwardly during a ditch burning operation. Thevehicle is adapted to be moved longitudinallyover a ditch5 and in such aposition as to straddle the ditch, as shown in Figure 2. Mounted on the1 frame 1 isafuel tank 6 in which the fuel oil utilized forburning'theweeds out of the ditch is carried and supplied to theburner.-

A seat 7 is secured to-the upper face of the tank: 6 forthe occupancy ofthe operator of the machine. I i

. Extending rearwardly and downwardly from the rear end'of the tank 6 isa flexible. feed pipe 8 into which oil passes on its way to the burner,said feeding of the oil being controlled by a valve 9 carried in thehorizontal portion of the pipe 8. The lowerend of the downwardly andrearwardly extending portion of the pipe 8 is connected by means of a T10 to a transversely disposed pipe 11, said pipe llhas connected to itsends longitudinally disposed pipes 12, which pipes are in turn connectedto a transversely disposed burner pipe 13, the burner pipe 13 is inparallel relation to the pipe 11, thereby extending transversely of theditch 5 in which weeds have collected and which ditch it is desired tobe cleared by destroying the weeds and trash that may have collectedtherein. The burner 13 substantially centrally thereof is provided witha downwardly extending segmental bend so that the flame from the burnerwill be projected against the entire transverse surface of the ditch andat the same time as the machine advances it will be seen that the ditchwill be entirelycleared of weeds and the like. By providing the burnerwith a centrally disposed segmental portion it will be seen that theportions 13; will overlie the side banks of the ditch and burn the weedstherefrom.

ing crops, the contact of the flame or the radiation of heat to saidgrowing crops will be prevented by the vertically disposed shields 14:which are secured to the vehicle axle as shown at 15. Extending upwardlythe pipe 8 and they also form means for Where the machine is usedadjacent grow nected as at 11 to a bell crank lever 11% Bell crank lever11 is pivotally mounted on the axle 2 and has connected to its arm 11 aconnecting bar 11 Connecting bar l1 is in turn pivotally connected as atll to an operating lever 11*, which is pivoted to the side of the tank 6and is provided with a dog 11 which cooperates with a toothed rack 11 Itwill be seen that by manipulat ing the lever 11, the burner may beraised clear of the ground when the same is not in use, for the reasonthat the pipe 8 is a flexible one. Lever 11* also provides means wherebythe burner may be adjusted and held in relation to the ground or thebottom of a ditch.

In operation the weed burner is placed in the position shown in Figure2, that is in a position to straddle the ditch 5. In this position itwill be seen that the semicircular downwardly extending portion of theburner willbe disposed in said ditch, also that the portions 13 of theburner will overlie the edges of the ditch so that the weeds adjacentthe ditch will also be destroyed. However it is to be understood thatthe entire burner may, where a ditch is very wide,

' be disposed in the ditch itself as shown in Figure 1.

1 ,asaass The invention having been set forth what is claimed as new anduseful is A weed burner and destroyer comprising a frame, a transverselydisposed axle carried by said frame, a fuel tank disposed on the frame,wheels for supporting said axle, a transversely disposed frame formedfrom piping and disposed below and rearwardly of the axle, thetransversely disposed frame being rectangular shaped and provided withapertures in the rear section thereof, thereby forming a burner, aflexible pipe connection between the transversely disposed framecentrally of the forward portion thereof and the tank, arms pivotallyconnected to the axle and to the forward side of the transverselydisposed frame, a bell crank lever pivotally mounted on the axle to oneside of the tank, one arm of said bell crank lever having alinkconnection with the rear side of the transversely disposed frame, alever pivoted adjacent the side of the tank and a connecting rodconnecting the lever to the other arm'of the bell crank lever, saidlever forming means whereby the bell crank may be rocked on the axle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
